UNTTEE TATE PATENT QFFICE.

HENRY D. BLAKE, OF NEW HARTFORD, CONNECTICUT.

FURNITURE-CASTER.

Specification of Letters Patent No. 20,031, dated April 27, 1858.

To aZZ whom 'it 'may concern: v

Be it known that I, HENRY D. BLAKE, of New Hartford Center, Connecticut, have invented certain new and useful Improve-` ments in Casters; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in securing the spring with the pin and to the horn of the caster for the purpose of working in the groove in the plate and thus keeping the two parts of the caster together as will be hereinafter described.

In order that those skilled in the art may construct and use my invention I will proceed to describe its construction and operation.

In the accompanying drawings making a part of this specifieation-Figure 1 is a view of the parts of the caster secured together by means of the pin in the groove. Fig. 2, is a view of the parts of the caster with the plate removed. Fig. 3 is a view of the plate showing 'the means of attaching it to any de- Sired object. F ig. 4 is a view of the spring.

In the several figures, F, represents the ro-ller of the caster.

B represents the two arms between and to which the roller F, is secured.

E, is a pin secured to the horn of the caster; this pin is provided with a shoulder marked w, in Fig. 2.

c, is a small spring the form of which will be seen in Figs. 1 and Jerthere being a hole in this spring the pin passes through it and when the pin is secured to the horn, the spring (o) is secured also between the shoulder w, and the horn. The `pin being riveted to the horn the spring (o) is of course firmly secured.

A, is4 the plate of the caster and (a) is a fiange secured to it or formed on it for the purpose of securing it to any desired object by means of screws or nails.

((Z') is a groove in the plate into which the spring (a) enters and in this manner keeps 'the two parts of the caster together` In Operating this caster the plate A is secured to the object through the flange, or rim (a) by means of screws or nails. The pin is then made to enter the plate, the spring (c) catching in the groove cl, and thus sustaining the t-w'o parts together. The lower port-ion may be easily removed by simply pulling it gently, the spring giving and slpping out of the sustaning groove.

I am aware that the spring and groove have been employed before,-a groovel being made in the plate or socket tube, the spring secured in it, and catching on the groove made in the pin,-but this is inconvenient and expensive, hence I do not claim the spring or the grooveflmy claim being confined to the manner of securing and arranging the groove and spring for the purpose of making a cheaper article to the trade; but

lVhat I do claim as new and desire to secure by Letters Patent is- The within described arrangement of the several parts of the caster, constructed and operated in the manner and for the purpose hcrein fully set forth.
